Article
In 2015, which marked 35 years since Beaumont had worked at the site, we renewed excavations at Border Cave. Our primary aims were to reassess the stratigraphic context of the sedimentary and cultural sequence, gain insight into site formation processes, make a detailed study of organic remains, identify long term cultural trends, and characterize...

In nature, each mineral grain (quartz or feldspar) receives a dose rate (Dr) specific to its environment. The dose-rate distribution therefore reflects the micro-dosimetric context of grains of similar size. If all the grains were well bleached at deposition, this distribution is assumed to correspond, within uncertainties, with the distribution of...

Marine Isotope Stage (MIS) 5 and 4 are periods of major cultural innovations in the Middle Stone Age (MSA) of southern Africa. While extensive data is available for the coast, far less is known about the interior, in particular its central plateau. This is likely due to the large geographic extent of this area and a general paucity of caves and roc...
Article
Teeth are usually targeted for dating archaeological sites because they are the least prone to dissolution, in comparison with bones. However, despite this apparent resistance, teeth do undergo diagenesis, which needs to be accounted for in order to obtain accurate ages. In particular, the uptake of trace elements such as uranium in dental tissues...
Article
Coastal adaptations have been considered to play an important role in the bio-cultural evolution of early Homo sapiens and their dispersal out of Africa. In line with this assessment, recent years have seen increasing evidence for the exploitation of seafood from the Middle Stone Age (MSA) of northern and southern Africa. Yet, chronological control...

Luminescence ages are calculated by dividing an absorbed dose by the dose rate to which the natural dosimeter has been exposed. In practice, one measures an equivalent dose, De; in the absence of an alpha dose contribution, this should be indistinguishable from the dose absorbed in nature. Here we first review the relationship between absorbed dose...
